Print Guide

Hardware version: Arpeggio (latest)

Total print time about 80h

The whole print is available as a Bambu 3MF file here

Defaults

Unless a part says otherwise:

  • Material: PLA
  • 2 walls, 15% grid infill
  • Print 1 of each part
  • Supports: tree supports, build plate only, 0.5mm XY distance to part

The exceptions to the support default are the regular bearing block, the slip ring block, and the sunglasses — print these three without supports.

Covers, faces, fingers, geared levers, linkage, and parking hooks are all visible on the finished build, so pick their colors with the look of the finished robot in mind. Color is irrelevant for everything else.

Do not use PET for any gears. It squeaks.

Anchor

Cover top (2x) and Cover bottom (2x)

  • Visible — choose color to match walls or crown moulding
  • Print top cover upside down.
  • Glue together with cyanoacrylate

Frame (2x)

  • Print in PCTG or PETG-CF. Not PLA - this part needs strength and heat tolerance.
  • 2 walls, 22% adaptive cubic
  • Tree supports, build plate only, critical regions only, 0.5mm XY distance to part
  • Bambu super cool tack plate reccomended

Regular bearing block (1x) and Slip ring block (1x)

  • No supports
  • Print on side face

Spool A Power (1x), Spool A Regular (3x), Spool B (4x)

  • tree supports for recessed holes
  • Glue A's and B's together to create complete spools.

Stud mount (2x)

  • 5 wall thickness, 30% cubic infill. May be visible if you remove the anchors, so white PET-GF15 is a great choice.
  • Can be converted for tripod use by adding a 1/4" coarse thread insert to the hole at the bottom.

Sunglasses (2x)

  • No supports
  • Should match the color of the anchor cover and is externally visible, therefore the same white PLA as the cover.
  • 4 wall thickness, 30% cubic infill.

Tilt adapter (2x)

  • PLA any color
  • very fine details - 0.16mm layers.

Eyelet

Body stud mount (1x)

  • Print on the odd diagonal flag face since it's stronger than printing on the back.
  • match wall color
  • 100% infill
  • PET-GF15

Retainer (1x)

  • match color of other eyelet part

Gripper

Back plate (1x), Camera mount (1x), Mechanism lid (1x), Motor bracket (1x)

  • Default settings, color almost irrelevant, though small bits may be visible with the fingers open.

Flat Marker (1x)

  • If multicolor is available use flat_marker_colored.3mf
  • Otherwise print in white, and apply stickers.
  • 2 wall, 15% grid infill.

Hang Bar (1x)

  • Black PLA, Auxillary part for flat marker.

Drive gear (1x)

Warning common plastics are not strong enough for this part. Kits are shipped with a resin printed gear. But PCTG is the second best choice. PET squeaks. PLA breaks, PETG is too soft. Nylon and ABS are probably fine if you can print those.

  • 100% infill
  • PCTG with Nozzle temperature 265°C — higher than usual for this filament
  • 3 wall

Face Back (1x) and Face Front (1x)

  • Visible — choose color deliberately
  • It is a good idea to merge the parts in the slicer and print them with their open faces towards eachother so they share tree supports.

Finger (2x)

  • Visible — choose color deliberately
  • Otherwise default settings

Geared lever left (1x) and Geared lever right (1x)

  • Visible — choose color deliberately
  • Otherwise default settings

Linkage (2x) (part of the finger)

  • Visible — choose color deliberately
  • Otherwise default settings

Spacer (7x)

  • Default settings
  • three for the gripper, two for each anchor.

Odd Spacer 2 (2x)

  • Default settings
  • One for each anchor. It provides back support to the barrel jack.

Wrist pole helical gear (1x), Wrist removal block (1x), Wrist servo helical gear (1x)

  • Default settings, color irrelevant

Extras

Clip or Alligator Clip (4x)

  • Default settings, white
  • The alligator version is an alternative that works on bigger things.

Parking hook (1x) Parking support bar (1x)

  • Visible — match wall color
  • 2 wall, 11% cubic infill

Eyelet vice block (1x)

  • A jig for holding the eyelet so you can press the body, ring, an retainer together with a drill press.
